Samsung Galaxy S II HD LTE and Galaxy S II LTE official

Samsung Korea has unveiled two LTE versions of the Galaxy S II, the Samsung Galaxy S II LTE and the Samsung Galaxy S II HD LTE, the latter packing a huge 4.65-inch Super AMOLED HD display running at 1280 x 720 resolution. Each model totes a 1.5GHz dual-core processor, WiFi a/b/g/n and Bluetooth 3.0 along with 4G LTE support and NFC, though the Galaxy S II LTE makes do with a 4.5-inch WVGA panel as on the EPIC 4G Touch.

Both models have an 8-megapixel main camera with autofocus and Full HD video recording, aong with a front-facing camera for video calls. There's also 16GB of internal storage – plus a microSD card slot – and GSM/HSPA+ roaming for when you're outside of South Korea's 4G cosseting. Maybe most impressive is the thickness: both the Galaxy S II LTE and Galaxy S II HD LTE come in at 9.5mm deep, even accommodating a 1850 mAh battery.

Samsung will be offering the Galaxy S II LTE via SK Telecom as a carrier-exclusive, while the Galaxy S II HD LTE will go on sale through SK Telecom, KT and LG U+. No word on when – or indeed if – Samsung will bring either model to the US or Europe, but given the high-ppi appeal of HD displays we're guessing there'll be plenty of demand for them.

Earlier this month, Samsung unveiled another HD smartphone, the Galaxy Note. Larger again than the Galaxy S II HD LTE, the Note has a 5.3-inch Super AMOLED HD display which works with both finger-touch and with a special digital stylus. Its display runs at 1280 x 800 resolution; more information in our hands-on report.
